Yes, right! And you can see in the picture a new drilled hole, and an old one, where I already had put a screw in. So just slightly smaller. And as far as I know the clamps don‘t break the stranded wires. It was a problem with the screws in these terminal blocks, no? Atleast from experience, I haven‘t seen any broken wires. This silicone wire is just soo flexible, I like it, but I think solid core wire is even easier to put into the connectors.
